Yes, I want to keep people that are not mentally stable, have a criminal record, cannot exhibit the competency to handle a firearm to not have guns. I don't think it is reasonable to prohibit mentally stable, law abiding citizens from owning guns.
My son is currently on a combo hunting, dirt biking, snowboarding trip in the Eastern Sierras. He loves going out camping and hunting with his friends. Way more healthy than going to the Shanty or the Office, getting hammered and an STD from some random cougar hook up. Why do you want to prevent him from living a healthy life?
